Prepare for Rolling and Maintain Wet Edge

What happens here

Before starting to roll, ensure any cut-ins (painting along edges and corners with a brush) are being completed by a second person. This allows you to work immediately behind the cut-ins, maintaining a 'wet edge' where the rolled paint overlaps the freshly brushed paint. This technique is crucial to avoid lap marks and hat-banding (visible lines where brushed and rolled paint meet). Load your roller with an ample amount of primer by rolling it repeatedly in a paint tray. Start rolling from one end of the wall, typically left to right, placing the loaded roller in the middle of a section and working your way up and down.

Goal: Begin by having a second person perform cut-ins along the edges while you prepare your roller and paint, ensuring you work quickly to maintain a 'wet edge' as you roll to prevent visible paint lines.
